Cool! Normally, I'd recommend doing a sort of sand colored base after the primer, then doing darker washes on top. But I like the dry, excavated look yours has.
One thing I'll sometimes do (which I think would be similar to the leather gel) is to mix a bit of dark paint with Minwax Polycrylic satin. Lets you do a bit of a glaze, rather than a solid color, but it stays in place better than if you watered it down.
